Modification of the double direction approach for solving systems of nonlinear equations with application to Chandrasekhar’s Integral equation [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2022 This study aims to present an accelerated derivative-free method for solving systems of nonlinear equations using a double direction approach. The approach approximates the Jacobian using a suitably formed diag-onal matrix by applying the acceleration ...

An α-Model Parametrization Algorithm for Optimization with Differential-Algebraic Equations
Applied Sciences, 2022 An optimization task with nonlinear differential-algebraic equations (DAEs) was approached. In special cases in heat and mass transfer engineering, a classical direct shooting approach cannot provide a solution of the DAE system, even in a relatively ...

Chiral flows can induce neck formation in viscoelastic surfaces
New Journal of Physics, 2023 The cell cortex is an active viscoelastic self-deforming sheet at the periphery of animal cells. It constricts animal cells during cell division. For some egg cells, the actomyosin cortex was shown to exhibit counter-rotating chiral flows along the axis ...
